摘要
首先应用状态脉冲反馈控制的理论,建立了无公害害虫治理中的数学模型,并且对所建的模型进行定性分析,利用微分方程几何理论中后续函数法得到系统的阶一周期解存在的充分条件,证明该周期解是轨道渐近稳定的,同时利用数值模拟的手段讨论了系统在害虫治理中的应用意义.
In this paper,a non-polluted pest control model is firstly established by using statedependent impulses feedback control theory.Further,by using successor function of differential equation geometry rules,the sufficient conditions for the existence and orbitally asymptotic stability of first order periodic solution are obtained.Finally,Numerical results show that the system we considered are full of application meaning on the pest control management.
